Abstract: On décrit un système de navigation équipé d'une interface utilisateur graphique affichant une pluralité d'icônes. Une icône activée sélectivement par un dispositif d'entrée utilisateur s'agrandit, s'anime et présente une bulle de texte indiquant la fonction de l'icône. Quelques-unes des icônes sont associées à une pluralité de fonctionnalités potentielles pour le système de navigation. Les icônes s'animent par l'affichage séquentielle d'une pluralité d'images. La première image est une mémoire graphique complète d'images de base qui inclut des informations permettant d'afficher tous les pixels de l'icône. La deuxième image est affichée par changement des seuls pixels qui sont différents entre la première image et la deuxième image, sur la base d'un fichier de transit n'incluant que des informations relatives aux pixels à changer. Un deuxième fichier de transit indique les pixels à changer entre la deuxième image et la troisième image, ainsi de suite. Pour les icônes présentant de nombreuses images potentielles, plusieurs images de base peuvent être produites de manière à pouvoir atteindre plus rapidement un état, quel qu'il soit.

L'électrode, trouvant une application dans une batterie de stockage à l'hydrure de nickel, fait preuve d'une charge et décharge très efficaces tout en assumant le reste des fonctions d'une batterie. Elle a l'avantage d'être peu coûteuse et facile à recycler.
Patent CA-2335086-A1 (CA)
Inventor: D ANGELO MICHAEL R
IPC: G08B21/02
Filed: 1999-04-16
Abstract: La présente invention concerne un système antivol sensible au mouvement pour articles portables, qui fait appel à une communication bidirectionnelle entre l'unité antivol installée dans l'article portable ou fixée sur celui-ci et l'unité de contrôle portée par le propriétaire. Le dispositif antivol communique les alertes à l'unité de contrôle tout en permettant à l'utilisateur de filtrer les fausses alertes et de déclencher une alarme sur l'article portable dans le cas d'une alerte justifiée. Un algorithme de suppression d'alerte basé sur un calcul de durée permet de transporter le système à l'état armé sans créer d'alertes fréquentes au niveau de l'unité de contrôle. Une deuxième fonction d'alarme choisie par un commutateur de modes déclenche automatiquement une alarme en réponse à un mouvement conforme à une séquence d'alarme adaptative. L'alarme adaptative fait varier l'alarme en réponse à la fréquence et la durée du mouvement de manière qu'un mouvement isolé déclenche un avertissement, tandis qu'un mouvement persistant déclenche une alarme complète.

Title: Method for making a non-contact smart card with an antenna support made of fibrous material
Inventor: DELENNE SEBASTIEN
IPC: B42D15/10
Filed: 2000-11-28
Abstract: The present invention relates to a contactless smart card manufacturing process and more specifically to a manufacturing process for a contactless smart card for which the antenna is on a fibrous material such as paper. This process includes a manufacturing step to screen print the antenna onto the support, a step to bond the contacts of the chip onto the antenna support using conductive glue, and a step designed to laminate the card body onto the antenna support by hot press molding. Cutouts made in the corners of the antenna support prior to the lamination step enable the card bodies to be bonded together. The card thus obtained allows a posteriori viewing of any mechanical misuse to which it may have been subjected (extreme bending).
